    A WAN connects computers and LANs in different cities or countries via telephone lines, satellites
                     and fibre optic cables. A repeater is used in a WAN to extend the signal over a distance.

                     The Internet is an example of a WAN.

                     These are privately owned networks. PAN is used to establish the communication amongst the
                     computers within the range of 20 to 30 feet. It can be wired or wireless.

                       The concept of a PAN was first introduced by Thomas Zimmerman at M.I.T.'s Media Lab. It
                       was later supported by IBM's Almaden research lab.

                     geographical areas, for example, college campus,                                                Lab
